M. curta is known to be an active diel migrant, and occasionally is found in high abundances in the neuston at the surface. Normally by day it is a shallow mesopelagic species. Most records at high latitudes (>45°) have been for the late summer and autumn months of the respective hemispheres, so it may not be a year-round resident at these higher latitudes. Adult females occur regularly, albeit in small numbers, at bathypelagic depths, so a fraction of the population may be undertaking a life-cycle migration into deep water.
